Sorry I didn't look at this earlier.

(define-key map [remap notmuch-help] 
            (notmuch-pick-close-message-pane-and #'notmuch-help))
?  (And the same for the others)

That way if the user changes notmuch-common-keymap bindings in simple
ways, pick should stay in sync.  And if they change them in
complicated ways (say, writing their own notmuch-search wrapper or
something), pick should more or less gracefully de-sync.
